Short-distance Transport of Resources02:12

Short-distance Transport of Resources

16.3K
Short-distance transport refers to transport that occurs over a distance of just 2-3 cells, crossing the plasma membrane in the process. Small uncharged molecules, such as oxygen, carbon dioxide, and water, can diffuse across the plasma membrane on their own. In contrast, ions and larger molecules require the assistance of transport proteins due to their charge or size. Transport across membranes also occurs within individual cells, playing a variety of essential roles for the plant as a whole.

Social Traps

22.7K
Social traps are negative situations where people get caught in a direction or relationship that later proves to be unpleasant, with no easy way to back out of or avoid. The concept was orignally introduced by John Platt who applied psychology to Garrett Hardin's "Tragedy of the Commons", where in New England herd owners could let their cattle graze in the common ground. This situation seems like a good idea, but an individual could have an advantage. If they owned...

ABC Transporters: Importer01:27

ABC Transporters: Importer

2.8K
ATP-binding cassette or ABC transporters are a class of ATP-driven pumps that hydrolyze ATP to move solutes across the membrane. They can be grouped into importers and exporters. While exporters are present in all domains of life, importers exist only in bacteria and some plants.
In bacteria, based on the number of transmembrane helices and the chemical nature of their substrates, the ABC importers can be divided into three types:

ABC Transporters: Exporter01:31

ABC Transporters: Exporter

4.6K
ATP-binding cassette or ABC transporter is the largest superfamily of integral membrane proteins. The transporters have transmembrane-binding domains (TMDs) and nucleotide-binding domains (NBDs). The TMDs are specific to their substrates, whereas the NBDs are similar to engines that complete ATP hydrolysis to complete the substrate transport. They can be full transporters consisting of two TMDs and NBDs, half transporters with one TMD and NBD, while some encoded with a single TMD or NBD are...

Transmission-based Precautions II: Airborne and Protective Environment

1.4K
Transmission-based precautions are for patients infected or suspected to be infected (or colonized) with organisms posing a significant risk to others. The transmission precautions include airborne and protective environment precautions.
Airborne precautions:
Use airborne precautions when treating patients known or suspected to have diseases that spread through the air—for example, tuberculosis or measles. These organisms are present in smaller droplets expelled by an infected person and...

Area of Science:

  • Epidemiology and Public Health
  • Operations Research
  • Network Science

Background:

  • Pandemics like COVID-19 highlight societal vulnerability and the need for effective outbreak containment strategies.
  • Restricting population movement is a critical measure, but decisions require informed, optimized approaches.

Purpose of the Study:

  • To propose the Early-stage Transportation Lock-down and Quarantine Problem (TLQP) for optimizing transportation infrastructure restrictions during pandemics.
  • To develop a decision framework for minimizing the social cost of movement restrictions.

Main Methods:

  • Integration of a network-based Susceptible-Exposed-Infectious-Recovered (SEIR) model with a combinatorial optimization framework.
  • Development of a heuristic algorithm combining Effective Distance (ED) path and Cost-Effective Lazy Forward (CELF) for intractable problem-solving.

Main Results:

  • The TLQP framework provides a method to identify optimal transportation network segments for lockdown to mitigate pandemic spread.
  • Experiments on global COVID-19 spread demonstrate the model's utility in guiding national protective measures.

Conclusions:

  • The TLQP offers a valuable tool for informed decision-making in pandemic response, balancing public health with socio-economic impact.
  • This study contributes to the strategic orchestration of measures for managing current and future epidemic outbreaks effectively.
